I have next TimeLine Chart
google.setOnLoadCallback(drawChart);
function drawChart() {
var container = document.getElementById('timechart');
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'string', id: 'Room' });
dataTable.addColumn({ type: 'string', id: 'Name' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });
dataTable.addRows([
[ 'Magnolia Room', 'row 1', new Date(0,0,0,9,0,0), new Date(0,0,0,
14,0,0) ],
[ 'Magnolia Room', 'row 2', new Date(0,0,0,14,30,0), new Date(0,0,0,
16,0,0) ],
[ 'Magnolia Room', 'row 3', new Date(0,0,0,16,30,0), new Date(0,0,0,
18,0,0) ],
[ 'Gladiolus Room', 'row 4', new Date(0,0,0,12,30,0), new Date(0,0,0,
14,0,0) ],
[ 'Gladiolus Room', 'row 5', new Date(0,0,0,14,30,0), new Date(0,0,0,
16,0,0) ],
[ 'Gladiolus Room', 'row 6', new Date(0,0,0,16,30,0), new Date(0,0,0,
18,0,0) ],
[ 'Petunia Room', 'row 7', new Date(0,0,0,12,30,0), new Date(0,0,0,
14,0,0) ],
[ 'Petunia Room', 'row 8', new Date(0,0,0,14,30,0), new Date(0,0,0,
16,0,0) ],
[ 'Petunia Room', 'row 9', new Date(0,0,0,16,30,0), new Date(0,0,0,
18,00,0) ]]);
var options = {
colors: ['#cbb69d', '#603913', '#c69c6e','#cbb69d', '#603913', '#c69c6e'
,'#cbb69d', '#603913', '#c69c6e'],
backgroundColor: '#fff',
enableInteractivity: false,
};
chart.draw(dataTable, options);
google.visualization.events.addListener(chart, 'select', selectHandler);
function selectHandler(){
var selectedItem = chart.getSelection();
if (selectedItem) {
var value = dataTable.getValue(getSelection.row,1); //row is
undefined
alert('The user selected ' + value);
}
}
}
I need to see "The user selected row 1", when first row was clicked.
Where did I go wrong?
PS. Sorry for my bad English.
